Document Type and Number:
WIPO Patent Application WO/2018/124457
Kind Code:
A1
Abstract:
Disclosed are a linear light source using ultraviolet LEDs, and a photopolymer 3D printer comprising the linear light source. The linear light source according to the present invention comprises: a substrate distanced from a polymer case of the photopolymer 3D printer; and an ultraviolet LED array in which a plurality of ultraviolet LEDs, which project ultraviolet rays toward the polymer case, are arranged on the substrate in multiple rows in the X-axis direction, wherein the arrangement of the multiple columns in the Y-axis direction is at an oblique angle to the multiple rows.
